What reviewers say
Both reviewers praise deep blacks, colour and detail for the price. What Hi-Fi? likes the upscaling but finds weaker detail at light and dark extremes and mildly muffled sound. RTINGS highlights wide viewing angles and low gaming lag, while noting limited HDR brightness, colour adjustment needs and visible banding in some gradients.
